Safety and Structural Concerns

Caution: Before igniting the pilot or burners, perform the following inspections and verifications: Check glass gasket seal. Visually inspect glass gasket, especially at the corners of the glass piece. Gaskets that

bulge at corners can cause improper seals between the bulges that can cause exhaust leaks and lead to acrid smell concerns.

If facing materials are freshly painted or freshly polished (in cases of marble or granite), ensure the convection blower is running at Level 2 or Level 3 during the first two hours. After two hours of initial burn, allow fireplace to cool. Proceed with “How to Cure the Fireplace.”

This fireplace must be installed and serviced by a Mendota-approved serviceperson. Any adjustments to burner, pilot, logs, or coal bed must be made by a Mendota-approved service person.

If pilot goes out, always wait five minutes before attempting to relight pilot. Never block off convection air openings or paths. Always use Mendota decorative fronts and Mendota-

approved vent systems and vent caps. The Mendota direct vent fireplace may be placed within 16” of adjacent sidewalls. The fireplace may be

placed directly on concrete or wood flooring. An 8” combustible mantel may be installed at a minimum of 22" above the top of the heat outlet (48 ½” up

from the floor level of this fireplace). Non-combustible (marble, brick, stone, etc.) mantels can be installed at any desired height above the top convection air opening.

A non-combustible hearth protector with a total insulation rating of R-1 is required when installing this fireplace directly on the floor and must extend a minimum of 18" in front of the fireplace. For every 1” the fireplace is raised off the floor, the depth of the hearth protector may be reduced by 2”. If fireplace is raised off the floor 6" or more, no hearth protector is required.

Venting Requirements

This Mendota fireplace can be vented using many available listed direct vent coaxial pipe (8”x5”) off the top.

Approved brands of vent components include DuraVent, AmeriVent, ICC, Selkirk, Olympia, and Security vent pipes and venting components. Closely follow venting locations, directions, and requirements. Observe the

restrictions relating to vent position on exterior of home. Be sure all vent pipe sections are fully twist-locked and leak-proof. Be sure 1000ºF silicate stove sealant is used on the inner pipe joints of all Simpson DuraVent pipe components and all adjustable pipe sections.

WARNING

FIRE RISK/ODOR RISK

• Install appliance on hard metal or wood surfaces extending full width and depth of this fireplace.

• An R-1 Rated Hearth Protection Pad [1 ½” thick maximum] is required unless this fireplace is elevated at least 6”

above floor level of the room. For every 1” this fireplace is elevated, you may reduce the hearth pad depth by 2”. If this fireplace is elevated 6” or higher, no hearth protection pad is required.

• Do not install this fireplace directly on carpeting, vinyl, or any combustible material other than wood. Construct chase to all clearance specifications in manual.

• Locate and install appliance to all clearance specifications in manual.

• Verify glass gasket seal before firing unit the first time. Verify proper latching of glass frame onto unit body.

Page 12

FV36 85-03-01014

Heating Performance

With its high heat output, this Mendota fireplace will heat a large area of the home if located properly to maximize heat/air circulation. Air movement options for maximizing heat circulation that can be considered are the continuous operation of central heating furnace blowers or ceiling fans. The most efficient method for overall heat distribution within a single room is a ceiling fan. The heat output of the fireplace can be reduced by turning off the rear burner and reducing flame height using the remote control. Blowers can be turned down or turned off to reduce heat distribution.

Aesthetic Considerations

Burning or static fireplaces are a major aesthetic focus in any room. Position your gas fireplace as you would a television set. A well-placed Mendota fireplace will be a continuing source of comfort and interest. Corner installations will afford you the greatest potential for viewing in many rooms. This fireplace may be installed in an elevated position as long as 72” minimum distance is provided between the floor level of this fireplace and the room’s ceiling surface.

Manual Gas Shutoff Valve Installation Requirement

A manual shutoff ball valve is factory installed in the fireplace and is accessible through the air gap on the left of the glass frame. Use the glass latch tool to operate the shutoff ball valve. If local building codes require, obtain an external wall-mounted manual gas shutoff valve approved per local gas plumbing codes and install per local gas plumbing codes in the specified location.

FV36 85-03-01014

INSTALLING THE FIREPLACE

Framing the Fireplace

The rough framing dimensions given are the minimum allowed framing dimensions. Be sure when planning the framing of the unit that adequate space to hook up the gas and electrical on the left side of the unit.

After the fireplace is in place the front of the unit can be framed into the final width of 43”. This will allow finishing material to be installed around the unit.

Special Framing Note: If the fireplace is to be recessed in a cavity deeper than 20”, all framing and finishing materials protruding past the front face of this fireplace must be of the non-combustible variety.

WARNING

FIRE RISK ODOR RISK

• Install appliance on hard metal or wood surfaces extending full width and depth of this fireplace.

• Do not install this fireplace directly on carpeting, vinyl or any combustible material other than wood. Construct chase to

all clearance specifications in manual.

• Locate and install appliance to all clearance specifications in manual.

WALL THIMBLE ROUGH FRAMING

Constructing the Fireplace Chase

A chase is a vertical box-like structure built to enclose this fireplace and its vent system. Vertical vents that run on the outside of a building may be, but are not required to be, installed inside a chase.

Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes must be followed.

Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building envelope in any manner.

Wall, ceiling, base plate, and, if applicable, cantilever floor of the chase should be insulated. Vapor and air infiltration barriers should be installed in the chase as per regional codes for the rest of the home. In addition, in regions where cold air infiltration may be an issue, the inside surfaces of the chase may be sheet rocked and taped for maximum air tightness.

To further prevent drafts, the fire stops should be caulked with high-temperature caulk to seal the gaps. Gas line holes and other openings should be caulked with high-temperature caulk or stuffed with unfaced insulation. If the fireplace is being installed on a cement slab, a layer of plywood may be placed underneath this fireplace to prevent conducting cold into the room.

Page 22

FV36 85-03-01014

Mantel Clearances

Mantel clearances for this fireplace may be measured from the top of the convection air opening or the floor level of this fireplace. The location that is referenced normally to measure mantel clearances is the top

of the convection air opening. The chart and diagram, in this page, provide all the reference dimensional information necessary in determining the distance a combustible mantel may protrude out from the face surface of this fireplace. The chart shows the distance from the fireplace face that the combustible mantel may protrude outward at a distance up from floor level of this fireplace.

If you prefer to take measurements from the top of the convection air opening, note that the top of the convection air opening is 26 ½” up from the floor level of this fireplace.

Warning: Make proper use of this chart. Do not compromise the specifications contained in this chart. Failure to adhere to proper clearances required to combustibles may cause overheating of the mantel.

Note: For mantels that protrude more than 8” from the front surface of the fireplace, use a rise and run of (1:1) to calculate the required height of the mantel.

Example: You have a 12" mantel. To calculate the height above the convection air opening the equation would be

14" + 12" = 26" above the convection air opening.

HEARTH PROTECTION PAD REQUIREMENTS

Hearth Protection R Rating: MINIMUM R-1 is required.

Consult the R-1 Value Table for reference.

Hearth Pad Guide

This fireplace requires an R-1 rated hearth protection 18” deep and no less than the width of the unit. For every 1” the unit is raised, the hearth depth can be reduced by 2”. Once the unit is raised 6” or more, no hearth protection is required.

See the suitable backer R-Value Table. Micore is a recommended product for this application. The R-value requirement is achieved with only ½” product. Any common building material may be used as long as the R-1 value is achieved.

The fireplace comes equipped with a hearth finish guide 1 ½” from the bottom of the fireplace. If the hearth pad is

going to be thicker than 1 ½”,

the unit must be raised accordingly.

The bottom hearth guide is attached to the unit with plastic rivets. The rivets can be cut with a razor knife and the guide removed after the hearth has been constructed.

This fireplace may be installed in an elevated position by creating an elevated deck and an appropriate framed enclosure.

Note: This fireplace may be elevated but must allow a minimum of 72” distance between this fireplace’s floor level and the ceiling of the room.

All hearth pads must be non-combustible (metal, brick, stone, or mineral fiberboard).

• Do not use any combustible material to protect the floor in front of this fireplace. The hearth protection pad must be rated at R-1 minimum, and it must extend 18” in front of the fireplace face if the fireplace is installed at floor level.

• To achieve this required R-rating, Mendota strongly suggests that you employ ½” thick mineral/ceramic board as the base substrate on top of the combustible floor construction or combustible raised hearth structure before you place additional finishing materials or natural stone products to achieve an R-1.0 minimum rating. Refer to the RRating specification tables in this manual.

• For applications where you want to attach tiles or stone slabs to the mineral/ceramic board, follow the instructions supplied by the board manufacturer.

FRAMING DEPTH and FINISHING GUIDES

Finishing Materials Installation

Finishing Guides

This fireplace comes with one standard finishing guide that will be used with any inside finish decorative front. Door installation will require the use of a faceplate. Grace and Willowbrook fronts have optional finishing applications depending on what wall finishing material and what finished look you want to achieve. Refer to the Grace/Willowbrook finishing guide options.

It is important to know what wall finish is being used and what finish option is preferred prior to unit installation when choosing a Grace or Willowbrook front.

When the wall finish material will exceed 2 ½” in depth, the Grace or Willowbrook (Option 3) guide kit will be

required to allow the decorative front to install properly. All finish guides, standard or optional, protrude 1” from the face of the unit. Factory guides are installed with

rivets and can be removed with a ⅛” drill bit. The finish guide used should be permanently left in place.

Framing Depth and Finishing Materials

Recommended Backing Materials Over Non-Combustible Zone

The minimum framing depth for this fireplace is 20”. This is a fixed depth required for all installations—see General Specifications and Planning the Installation sections of this manual.

Mendota strongly recommends using a minimum ½” non-combustible backer material—see suitable backer material, R-Value Table—using the highest R-value available when installing any finish material (e.g., tile, marble, granite, faux stone) over the non-combustible zone of this fireplace.

For applications where you are installing faux stone, stone, brick, tile, etc., metal lath screen can be attached to the backer material and a scratch coat of thinset mortar can be applied.

Mendota strongly recommends not using mortar blends with polymer additives or any premix mastics or any adhering compounds with chemical base such as PL construction adhesives or silicone. Use of these products will cause a high likelihood of offgasing odors.

For the installation of solid slab stone (e.g., granite, marble, slate), Mendota recommends using a minimum ½” non-combustible backer material of the highest R-value available. See suitable backer material, R-Value Table. Caution: These materials are natural products and are prone to internal week points such as air pockets and stress cracks. These natural products are prone to surface cracking under heat stress (expansion and contraction).

To minimize the possibility of surface cracking, Mendota strongly recommends:

• Not to adhere the finish material to the backer material within the non-combustible zone of the fireplace.

• Not to install the natural stone in a one-piece application—allow expansion joints by installing a multi-piece application.

For the installation of a smooth painted wall application, Mendota strongly recommends a minimum 1” non- combustible wall board using the highest R-value available. See suitable backer material and R-Value Table.

To reduce the possibility of surface cracking Promat, Promafour, or Skamole, where available, is highly recommended for this application, using manufacturer specific joint fillers and skim coat materials.

Page 25

FV36 85-03-01014

Do not use Durarock Next Gen or Wonderboard. These products contain styrene fillers and polymer meshing that will break down under heat exposure and create odors.

Do not leave joints above or at the corners of the fireplace and always allow the wall material to float over the non-combustible zone. Do not attach finish material to the metal face of the fireplace. Only attach finish materials to wall framing members.

Choose skim coat and paint materials that will withstand constant temperatures in excess of 200°F.

Hearth Pad Requirements

hearth protection is required.

Additional Application Caution for Finish Materials

If wood is being used around or in front of the fireplace—mantel or trim—you must comply with all clearance to combustibles described in this manual.

If wood has been chemically bleached or cleaned, ensure that no cleaner remains engrained in the wood surface prior to finish. Bleach, chemical cleaning compounds, and moisture content within the wood’s surface can cause paint blistering, cracking, or discoloring even under low-heat levels as it evaporates from the material surface.

Choose paints, stains, and finishes that can withstand constant temperatures in excess of 200°F. Caution: For smooth wall and natural stone finishes, the recommendations made in this installation manual

are based on our research on preferred backer and finish materials for best results. Natural materials are prone to air pockets, voids, stress cracks, and internal imperfections created by nature.

Note: Mendota will not be responsible for and will not warranty a smooth wall or natural stone wall finish because of the vulnerability and uncertainty of these finish products under heat stress.

Paint Types Approved for Use

Industrial acrylic paints and alkyd-based paints: When selecting paint for applications on facings, mantels, corbels, or floors within 2’ in front of a fireplace raised 6” or higher, avoid off-the-shelf paints that may have

modifier additives used to increase “hiding” ability, accelerate drying times and curing times. Consult with a

reputable paint and sealant supplier and acquire industrial acrylic paints or alkyd-based paints.

Sealant Types Approved for Use

Heat-resistant polyurethane sealants: These are not damaged by prolonged exposure to raised temperatures. Many are flame resistant, meaning that they resist ignition when exposed to high temperatures and can insulate the substrate and delay damage to it. When selecting polyurethane for applications on facings, mantels, corbels, or floors within 3’ in front of a fireplace, avoid off-the-shelf urethane sealants that may have modifier additives used to accelerate drying times and curing times. Consult with a reputable paint and sealant supplier and acquire heat-resistant polyurethane sealants.

WILLOWBROOK/GRACE FRONT GUIDE OPTIONS

This unit comes with guides to ensure finish materials do not exceed the convection area of the fireplace. Some models come with additional guides for different front options.

There are three options for finishing the fireplace when installing a Grace or Willowbrook front.

Please read the following instruction before installing the finishing material on the front of the fireplace. If you have any questions about finishing the fireplace contact a Mendota dealer or the Mendota Service Department.

• For painted wall finishes, refer to this manual on suitable finishing materials.

• Remove any front, screen, or door prior to install of finish materials to avoid damage.

OPTION 1: INSTALLING THE FRONT ON TOP OF FINISHING MATERIAL

Note: No extra parts required.

Option 1 requires that your finish material be less than 2.5” thick, including backing materials and reasonably flat. If not, use Option 3.

• Use the inner guides that come on the fireplace.

• The guides are 1” deep. If your finish material is rough or lightly colored and extends past 1”, you

may see the material behind the screen at certain angles.

After the fireplace is installed and the finishing material is complete the front can be hung on the fireplace. The finished look is similar to hanging a picture frame on a wall where the frame protrudes out from the wall.

Because the screen is attached to the back of the Grace or Willowbrook front, there will be a ¾” gap between

the frame and wall. If you do not want this gap, but want the frame to mount over the finishing material, then consider using Option 2.

Page 28

FV36 85-03-01014

OPTION 2: INSTALLING THE FRONT ON TOP OF FINISHING MATERIALS WITH THE SCREEN RECESSESED

Note: Order “template kit” or Option 2 in the

pricing. Option 2 requires that

your finish material be

less than 2.5” thick

including backing materials and reasonably flat. If they are not, use Option 3.

Use the reference chart or pricing to ensure you have the necessary guides/templates.

OPTION 3: INSTALLING THE FRONT FLUSH OR RECESSED INTO THE WALL

Note: Must order guide kit Option 3. This option allows the

front to mount with any finish material. It is a “recessed” or “flush” finish.

Use the reference chart or pricing to see which guide kit is required for each model.

FV36 85-03-01014

GAS SUPPLY REQUIREMENTS

Correct gas pressure and proper gas supply line sizing is imperative to the successful performance of this Mendota gas fireplace. Be sure the gas supplier or plumber carefully checks for correct gas pressure and gas line sizing when installing the fireplace.

It is critical to carefully check for gas leaks when hooking up the fireplace—check with soap and water solution.

Be sure to install "approved" flex gas line with brass-to-brass fittings to prevent gas leaks at connections. Gas supply piping must include a drip leg to eliminate the possibility of contaminants entering the gas train.

Adhere strictly to local and national codes for entire installation. Correct gas pressure and proper gas supply line sizing is required.

Gas Supply Line Sizing

This Mendota gas fireplace comes equipped with a ½" NPT female inlet. Gas supply piping must enter the fireplace cabinet on the left side.

An approved manual shut-off ball valve, if required by local codes, must be installed at an accessible location. The fireplace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ PSIG (3.5 kPa).

The fireplace must be isolated from the gas supply piping system by closing its manual shut-off ball valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ PSIG (3.5 kPa).

A proper gas line diameter must be selected to run from the supply regulator to the fireplace. Refer to the following table for proper gas pipe diameters.

Strictly adhere to the correct pipe sizes.

Gas Pressure Requirements

Inlet and manifold gas pressure checking taps are located on gas valve. Perform inlet and outlet pressure tests before completing the facing installation. Remove valve access cover box on left side of fireplace to access the gas valve and all control components.

A qualified installer must take pressure measurements at these ports to verify and set the correct inlet gas pressures during initial installation. Outlet gas pressures are factory-set and cannot be field adjusted.

Note: Check for gas leaks with soap and water solution on all factory joints and field installed joints during first firing of this fireplace.

One of the main causes of operating problems with gas fireplaces can be improper gas pressure. Problems such as changes in flame color or configuration, gas pilot or burner outages, intermittent operation, changes in heat output, and excessive burner noise are nearly always the result of changes in gas pressure or improper gas pressure at the time of the installation.

The most important item to check during initial installation and the first thing to check when problems occur are the input and output gas pressures.

Gas is normally supplied to a residence at ½ PSI (13" – 15" WC (3 kPa). A pressure regulator is then placed outside the residence, near the gas meter, which drops this pressure to 7" WC (1.8 kPa) (natural gas). This "inches to inches" regulator is of adequate capacity to service the gas fireplaces (such as dryer, furnace, etc.). If this regulator's capacity is not sufficient to add the gas fireplace, an additional "inches to inches" regulator must be installed for the fireplace. The following table provides information on correct gas pressure requirements:

GAS PRESSURE REQUIREMENTS

Note: Ensure your gas supplier or plumber carefully follows this table.

Exception: Some codes allow 2-PSI (1.4 kPa) supplies to enter the residence, in which case "pounds to

inches" regulators are used.

Manifold pressure must be taken at the “output pressure" tap and inlet pressure at the "inlet pressure" tap with the burner operating by a qualified installer.

Perform pressure tests prior to installing fascia material around this fireplace.

Gas Input Rate Verification Requirements

Natural Gas Applications Gas Input Rate Verification Procedures

Verify main orifice size. The main orifice body has the orifice size stamped on it. Natural gas orifice size will be #38 (rear burner) and #44 (front burner) for all elevations.

Verify that the manifold gas pressure is within 3.5" WC +/- ⅛". Once setup, read the main home gas supply meter reading.

Write the initial reading here: Initial Gas Meter Reading is _______________ Therms. Turn off all other fireplaces and their pilot flame in the home. Run this fireplace for a period of 30 minutes on maximum flame size. Turn off main burner and pilot flame. Read the main home gas supply meter reading after the 30 minutes of burn time.

Write the reading here: Final Gas Meter Reading is _______________ Therms.

To calculate the following: Subtract Initial Gas Meter from Final Gas Meter Reading. This will yield the number of Therms used during the 30-minute burn time.

Write the number of Therms used here: _______________ Therms.

Multiply the Therms used by 200,000.

Write the result here: _________________Btu

The result must be within 5% of 44,000 Btu.

LP Gas Applications Gas Input Rate Verification Procedures

Verify the main orifice size. The main orifice body has the orifice size stamped on it. LP gas orifice size should be #54 (front and rear burners) for all elevations.

Verify that the manifold gas pressure is within 10.0" WC +/- ⅛". Use the procedure above to calculate the Btu. The result must be within 5% of 44,000 Btu.

High-Altitude Derating

If you are derating this fireplace at a high altitude, attach the High-Altitude Deration Label to the back side of the wire harness plate located in the air gap under the firebox of the fireplace. Prior to attaching the labels, fill in all the information that is requested in these labels.

Pilot Flame and Main Burner Relationship Verification

Prior to completing the conversion process, the qualified service technician must, light the pilot and verify the relationship between the pilot flames and the main burners. The pilot flames directed toward the propagation ports on the rear and front burner must overlap the propagation ports on the burners. The pilot flames must be a minimum of 1.0” long and must overlap the propagation ports on both the rear and front burners as shown in the diagram, below. Verify that the burner tubes ignite quickly and the burner flames propagate smoothly along the entire length of the burners.

Pilot Flame Length Adjustment

If the pilot flame length is too short and the system does not maintain a standing pilot, a qualified installer may increase the length of the pilot flames to meet the two requirements: Minimum pilot length to maintain a standing pilot and the pilot flames must be long enough to overlap the front and rear burner ports.

Attaching LP Gas Conversion Label

A printed informational label is included with the LP Gas Conversion Kit (as shown). Attach this label to the back surface of the wire diagram plate that is located in the convection air cavity below the firebox:

Checking Burner Ignition Characteristics

Once the conversion to LP gas and all the above steps have been completed, light the main burners. Use remote control to turn on pilot and burners. Main burner should now light immediately and flame should

not "lift" off burner. If there is any delay in ignition or if flame is "lifting off" burner, turn off burner and carefully check for proper installation of logs/coals, vent system and proper pilot flame impingement on burner. Logs or coals must not block pilot flame or main burner flame. Vent system must be leak proof.

FLUE VENTING INSTRUCTIONS

General Venting Information

The Mendota fireplace must be vented using the Mendota approved vent system components. Approved brands of vent components include DuraVent, AmeriVent, ICC, Selkirk, Olympia, and Security vent pipes and venting components. All warranties will be voided and serious fire, health, or other safety hazards may result

from any of the following actions: Installation by unauthorized personnel; installation of any damaged component; unauthorized modification of vent system; installation of any components not approved by Mendota; failure to meet all clearance requirements; failure to properly twist-lock and positively seal all components. Consult local building codes before beginning the

installation. Warning: Always maintain required clearances (air spaces) to

combustibles to prevent a fire hazard. Do not fill air spaces with insulation. Check installation instructions for minimum clearance requirements between the outer walls of the vent pipe and nearby combustible surfaces. Be sure to check the vent termination clearance requirements from decks, windows, soffit, gas regulators, air supply inlets, and public walkways, as specified in these installation instructions and local building codes.

Safety Precautions: 1) Wear gloves and safety glasses for protection; 2) exercise extreme caution when using ladders or on rooftops; and 3) be aware of electrical wiring locations in walls and ceilings.

This gas fireplace and vent system must be vented directly to the outside of the building and never attached to a chimney serving another solid fuel or gas burning fireplace. Each direct vent gas fireplace must have its own separate vent system. Common vent systems are prohibited.

To assure proper venting performance of this high-performance Mendota fireplace, it is critical that all brands of vent pipe sections are sealed tightly and leak-proof. This means that all pipe sections must be carefully rotated into the fully "twist-locked" position.

We strongly recommend that fixed length pipe sections be used in place of telescoping sections whenever possible. Note: Do not separate telescoping sections. They must be used as complete assemblies.

Note: When using vent pipe and components that do not incorporate a fiberglass or graphite gasket at the inner exhaust tube joints, you must use Milpak 1000°F silicate stove sealant (#65-06-00909). Aluminum foil tape may be used on the outer (air intake) pipe joint but is not mandatory. Local codes may vary. Contact the Mendota dealer for proper materials.

Component "Twist-Lock" Connection Procedure

DuraVent and American Metals pipe and fittings are designed with special twist-lock connections. Twist-lock procedure is as follows:

Four indentations, located on the female ends of pipes and fittings are designed to slide straight into the male ends of the adjacent pipes and fittings, by orienting the four pipe indentations so that they match and slide into the four entry slots on the male ends.

Push the pipe sections completely together then twist-lock one section clockwise, approximately ¼ turn until the two sections are fully locked. The female locking lugs will not be visible from the outside on the black pipe or fittings. They may be located by examining inside of the female ends.

Important Venting Configuration Notes

Note: Prior to installing at altitudes higher than 7,500’, understand the gas deration requirement and adjust burner gas orifices accordingly. If unable, please contact the Mendota technical service department for specific venting requirements and venting restrictions.

Maximum Horizontal Run

A. Maximum horizontal run allowed is 32’ if a vertical starter section that is between 4’ to 12’ is

connected directly to this fireplace’s flue starter collar and no more than three 90° elbows are used.

B. Maximum horizontal run allowed is 12” if a 9” starter vertical section then a 90° elbow is connected

directly to this fireplace’s flue starter collar.

Maximum Vent System Length

A. Combined total length of all straight pipe sections in the vent system must be less than 44’. B. Combined total length of all straight pipe sections in the vent system must be less than 44’ when

using three 90° elbows or equivalent and terminating the vent system horizontally.

C. Combined total length of all straight pipe sections in the vent system must be less than 44’ when

using four 90° elbows or equivalent and terminating vertically.

Using 90° Elbows

The fireplace allows maximum flexibility in the use of 90° elbows in the vent system. The length of the first

straight vertical section directly connected to the fireplace’s starter collar determines the maximum

horizontal run and the number of 90° elbows allowed for this fireplace. For vent systems that provide a starting vertical section that is 4’ to 12’, you may connect up to 32’ of

horizontal pipe and up to three 90° elbows. For all vertical terminations, four 90° elbows can be used the fourth elbow must point vertically.

Using 90° Elbows When the Initial Starter Vertical Section Is Less Than 4’

For vent systems that provide a starting vertical section less than 4’ the following rules apply:

a. You must use the Master Flue Venting Requirements Chart. b. A single 90° vertical-to-horizontal elbow is already calculated into the allowable maximum horizontal run.

The Venting Requirements Chart assumes that for all horizontal runs calculated, one 900 elbow is used within the venting system.

Note: Each additional 90° elbow reduces the maximum horizontal distance allowed by 3'. c. If you plan to use more than one 90° elbow within the vent system, first use the Venting Requirements

Chart and calculate the maximum horizontal run you are allowed based on the first vertical section connected directly to the fireplace. From this maximum horizontal run calculated, subtract 3’ for each additional 90° elbow you will use.

Example: Assume you are using a 3’ long starter vertical section. This should allow, per the Master Venting

Chart, 22 ½’ of horizontal run. If you want to use three 90° elbows, subtract 6’ for two elbows from the 22 ½’ maximum allowed (3’ for each elbow after the first elbow). This yields 16 ½ ’ as the maximum horizontal run that you are allowed to install using the 3’ vertical starter section.

Caution: If a vertical-to-horizontal discharge elbow or a horizontal-to-horizontal discharge elbow is enclosed

within a wall, floor or ceiling, a top air space clearance of 3" must be maintained above the entire body of the elbow.

Page 47

FV36 85-03-01014

Using 45° Elbows

Two 45° elbows may be used in place of one 90° elbow. On 45° runs, one foot of diagonal pipe is equal to 8 ½” horizontal run and 8 ½” vertical run. Two 45° elbows may be connected directly to the vent starter adapter on this fireplace to create an offset to provide the required clearances to combustible framing or sheathing materials.

Two 45° elbows may be connected directly to the top of this fireplace to create a horizontal offset. 32’ maximum horizontal run allowed with this offset configuration only if the first vertical section connected directly to the last 45° elbow is 4’ to 12’ long. For maximum allowable horizontal distances with the 45° offsets, see the Master Venting Configuration Chart.

Note: Each horizontally positioned 45° elbow reduces the maximum horizontal distance by 1½'.

Support: Horizontal runs of pipe will require one vent support for every 3’ of pipe.

Minimum Rise with Horizontal Termination

A maximum horizontal run of 12” is allowed if a 9” vertical starter section and one 90° elbow is connected directly to this fireplace’s flue starter collar. The horizontal centerline of the 90ºelbow will be 46 ⅜” up from the floor level of this fireplace.

See the Master Flue Venting Requirements Chart and figures below for specifics.

Use "fixed" pipe sections in place of adjustable pipe sections wherever possible. 1000ºF sealant must be used on all inner pipe joints that do not have factory-installed gasket material.

Always maintain 1" clearance from vent pipe sides and bottom to combustibles, 3" clearance on top of pipe on horizontal runs and on top of horizontal discharge elbows. Do not fill air spaces with insulation or other material.

Warning: Verify your venting matches these dimensions before cutting a hole in the wall. Exact measurement can vary depending on the manufacture of the venting.

1. Position fireplace in desired location. See guidelines on proper vent cap placement on the exterior of home. Check to determine if wall studs are in the way when venting system is attached. If this is the case, you may want to adjust the fireplace location or modify the exterior wall framing to allow the vent system to penetrate the wall.

2. Measure from the floor level of the fireplace up 46 ⅜” and mark wall directly at the center of where the vent pipe will penetrate the exterior wall.

3. Cut and frame a 10 ½” wide x 10 ½" high opening in the wall. The hole must be positioned so the vent system will have a ¼" rise per foot of run and be perpendicular to the wall. The height of the opening must be located to meet all local and national building codes. Do not allow the termination to be easily blocked or obstructed. If wall being penetrated is non-combustible material, e.g., masonry block, brick, etc., an 8” diameter hole is acceptable.

4. Attach the 9” straight section to the fireplace starter adapter. Attach a 90° elbow to the top of the 9” vertical starter section and rotate and lock in position. Attach a horizontal section to the 90° elbow. Be sure all vent component connections are in their fully twist-locked position and are leak-proof. Be sure 1000°F sealant is used on the inner pipe joints of all pipe sections manufactured by Simpson DuraVent. The length of the horizontal piece that fits through the wall will be determined by the location of the fireplace relative to the wall. For a normal installation where this fireplace is installed directly against an exterior wall constructed using 2x4 lumber or 2x6 lumber, only a 6” horizontal section is required. There must be a minimum of 1" air space clearance to combustibles from all vent components (3" above horizontal runs and horizontal discharge elbows).

5. A wall thimble must always be used when penetrating combustible wall materials.

6. From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and

tightly secure the cap to the wall with screws. Seal with a high-quality caulking.

Note: Combustible wall thickness must be 4" to 8" maximum. Vent cap must not be recessed into wall or siding.

Page 50

FV36 85-03-01014

Vertical Rise Horizontal Termination

The minimum vertical section required to be connected directly to the starter adapter on this fireplace is 4’ when used with a maximum horizontal run of 32’. If the total length of the vertical sections connected directly to the starter adapter on this fireplace is between 4’ and 12’, you are allowed a maximum 32’ horizontal run. This fireplace provides a maximum flexibility in the use of 90° elbows when more than 4’ of vertical starter section is connected to the starter collar. If 4’ or more vertical section is connected to the starter collar, you may use three 90° elbows for horizontal terminations. For other venting configurations within these maximum limits, see Master Venting Chart.

Combined total length of all pipe sections in the vent system should be less than 44’.

Note: The horizontal run of vent pipe must have a ¼" rise for every 1' of run toward the termination. Never allow the vent to run downward. This will cause high temperatures and the possibility of a fire.

Follow these steps to install venting:

1. Position fireplace in desired location. Check to determine if wall studs are in the way when vent system is attached. If this is the case you may want to adjust the fireplace location.

2. Locate where vent pipe will pass through any ceilings and will penetrate the outside wall. Since vent pipe sections "overlap," we suggest pre-assembling and measuring the total vent pipe run so you can more accurately locate the point where the vent pipe will penetrate the outside wall. Be sure all vent components are properly twist locked and leak-proof. Be sure 1000°F sealant is used in the inner pipe joints of all pipe sections manufactured by Simpson DuraVent.

3. Cut and frame a 10 ½” wide x 10 ½” high opening in the outside wall openings and 10” x 10” opening in ceiling openings. The outside wall hole must be positioned so the vent system will have a ¼" rise per foot on horizontal runs and be perpendicular to the wall. The height of the opening must be located to meet all building codes and not allow the termination to be easily blocked or obstructed. A ceiling fire stop spacer is required at any floor (ceiling) opening.

4. The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipe will require a

proper support every 3’ of vent pipe. There must be a minimum of 1" clearance to combustibles from all vent pieces on the sides and bottom and 3" above horizontal runs.

5. A wall thimble must always be used when penetrating combustible wall materials.

Note: Combustible wall thickness must be 4" to 8" maximum.

Note: Do not separate telescoping section. They be must be used as complete assemblies.

6. From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and tightly secure the vent cap to the wall with screws. Seal with high-quality caulking around the outer perimeter of the vent cap. Note: Vent cap should not be recessed into wall or siding.

Vertical Through-The-Roof Venting

The maximum vertical run of vent pipe is 40’ from the top of the fireplace. The fireplace will support a run of a maximum of 40’. Maintain 1" air space clearances on all sides of vents.

If an offset is required directly on top of the fireplace, two 45° elbows may be connected directly to the top of this fireplace to create a horizontal offset then to run upwards vertically. Doing so will continue to allow the use of the 40’ maximum vertical run.

Follow these steps to install venting:

1. Place the fireplace in its desired location. Drop a plum bob from the ceiling to the position of the fireplace flue exit. Mark the location where the vent will penetrate the ceiling. Drill a small hole at this point. Next, drop a plum bob from the roof to the hole previously drilled in the ceiling. Mark and drill the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters or other framing will obstruct the venting system. You may wish to relocate the fireplace or to offset to avoid cutting load bearing members.

2. Cut and frame a 10" x 10" opening in the ceiling, centered on the hole drilled in Step No. 1.

3. To determine the length of the vent pipe required, measure the distance from the fireplace flue outlet to the ceiling, the ceiling thickness, and the vertical rise in the attic or second story and allow sufficient vent height above roofline. For two-story installations, fire stops are required at each floor level. If an offset is needed in the attic, additional pipe and elbows will be required.

4. Assemble the desired lengths of vent pipe and elbows to reach from the fireplace flue outlet. Ensure that all vent pipe and elbow connections are in their fully twist-lock position and that inner pipe joints (DuraVent only) are sealed and are leak-proof. Maintain 1" airspace clearances to combustibles (3" above horizontal runs). Cut a 10" x 10" opening in the roof, centered in the small drilled hole placed in the roof in No. 1. The opening should be a sufficient size to meet all clearance requirements. Continue to assemble lengths of pipe and elbows necessary to reach up through the roofline. Galvanized pipe and elbows may be used in the attic as well as above the roofline. The galvanized finish is desirable above the roofline due to its higher corrosive resistance.

5. If an offset is necessary, it is important to support the vent pipe every 3’ to avoid excessive stress on the elbows and possible separation. Wall straps are available for this purpose.

6. Slip the flashing over the pipe sections protruding through the roof. Secure the base of the flashing to the roof with roofing nails and seal flashing to roof. Ensure the roofing material overlaps the top edge of the flashing. Verify you have at least the minimum clearance to combustibles at the roofline.

7. Continue to add pipe sections until the pipe and the vent cap meet the minimum building code requirements.

8. For multi-story vertical installation, a ceiling fire stop is required at the second floor and any subsequent floors. The opening should be framed to 10" x 10" inside dimensions.

9. Any occupied areas above the first floor, including closets and storage spaces, which the vertical vent passes through, must be enclosed. The enclosure may be framed and sheet rocked with standard construction materials, however, be sure to maintain minimum allowable clearances between the outside of the vent pipe and the combustible surfaces of the enclosure.

Vertical Through-The-Roof Venting Using Four 90° Elbows

In extreme situations, four 90° elbows may be required to reach a proper exit point for the vent system. Mendota has spent considerable time and effort in the design of this fireplace and its venting system. Through this effort, Mendota has been able to certify the use of four 90° elbows when terminating vertically.

The use of four 90° elbows must meet some minimum prerequisites:

➢ Prerequisite 1: The vent system must terminate vertically using a vertical vent cap. ➢ Prerequisite 2: There must be a minimum 4’ of vertical starter section connected directly to the top

of this fireplace.

LOG SET INSTALLATION

Warning: Logs are breakable!

It is important to handle each log package and every log piece/assembly with extra care.

Breakage is the installer’s responsibility and is not covered by the Warranty Policy.

To access the log set:

1. Open the log set box and gently remove the foam packages and lay them on the floor.

2. Use a utility knife to cut tape strips that secure foam package tops to foam package bottoms.

3. Lift off foam package top slowly and carefully. If you find that the foam package is upside down, reverse it before attempting to separate the top and bottom foam trays.

To position each log correctly, refer to the specific log set instruction manual provided with the log set.

FV36 85-03-01014

INITIAL INSTALLER STARTUP INFORMATION

Caution: Ensure glass is properly sealed and ensure there are no combustibles near or on the fireplace. Refer to the installation section to make sure that finish materials have been applied with approved materials and clearances have been met. Failure to do so can result in odor, injury, or loss of life.

Step 1: Expelling Initial Smoke and Odors

• Complete the installation of any surround, front, doors, or safety screen.

• Turn on the fireplace in the Manual (Off) thermostat mode.

• Set the flame height to Hi.

• Set the fan speed control to Level 3.

• Run the fireplace with these settings for a minimum of 2 hours. Then turn off the fireplace and let it

cool.

Attention: It is important that the blowers are on during this step to prevent the curing smoke from staining the wall finish above the fireplace. Mendota recommends completing Step 1 prior to installation of wall finish materials. Visible smoke and odor is expected during this step. If desired, disable smoke alarms before this step. Smoke from the initial cure may set off smoke alarms. Open doors and windows to circulate fresh air.

Step 2: High Heat Curing Cycle

• Turn on the fireplace in the Manual (Off) thermostat mode.

• Set the flame height to Hi.

• Set the fan speed control to Off.

• Run the fireplace with these settings until curing odors have diminished.

• When odors have diminished, leave the fireplace on and continue to Step 3.

Attention: Odors initially may be strong. Open doors and windows to circulate fresh air if needed. Step 3: Final Curing Cycle

• Set the fan speed control to Level 1.

• If any new curing odors are detected, continue to run the fireplace with this setting until the curing

odors have diminished.

Attention: Slight odors may still be noticeable on future startups of the fireplace. These will diminish over time as the fireplace is used.

Additional Curing Information It is not unusual for a fireplace to require more than 10 continuous hours on high for curing odors to

diminish. There are variables that can extend or shorten the curing time, such as decorative fronts, doors,

facing materials, and their applications. Finish materials around the fireplace are subject to high temperatures. Finishing materials used over the

fireplace in the non-combustible zone can reach temperatures around 350° F. Materials used around the fireplace must be rated for these temperatures. Failure to use adequate materials can result in odor problems. Reference the “Additional Application Caution for Finish Materials” section of the installation manual for information on appropriate finishing materials.

It is normal for surfaces around the fireplace to be too hot to touch. Provided that all clearances and R-value requirements in the installation manual have been met, this is not a safety concern. Be aware that any material used around the fireplace will heat up and has the potential to cause odor issues. Adhesives, glue, wall substrate, wall finish material, paints, and polishes are common materials that if used incorrectly will cause odor issues. Mendota is not responsible for any odor issues caused by materials used around the

fireplace.

ADJUSTING FLAME APPEARANCE

Both the burner air shutters and the fireplace’s exhaust damper can be used to adjust and fine tune the fireplace’s flame appearance. Always let fireplace burn for at least 30 minutes minimum before making final adjustments. The flame’s appearance will change as the fireplace heats up.

Air Shutter Adjustments

Be sure burner and logs are properly installed (refer to the specific log set installation manual). After burner has been properly installed and operated for at least 30 minutes, small additional adjustments to the air shutter may be necessary for final flame appearance.

Note: Start with the burner air shutters set at ⅛” open for natural gas and ⅜” open for LP gas. The burner shutters can be manipulated with the fireplace operating. Opening the shutter will yield shorter, bluer

flames, and closing the shutter will yield taller, yellower flames.

The burner air shutter adjustment cables are located in the air gap on the left side of the glass door frame. The top cable will adjust the rear burner and the bottom cable will adjust the front burner. To open or close the air shutter insert the glass latch tool tip in the ring terminal’s ring hole. Push the cable to close the air

shutter or pull on the cable to open the air shutter.

Procedure for Adjusting Air Shutters

1. Install logs and glass frame and burn unit for 30 minutes.

2. After 30 minutes if flame is too "blue" close air shutters until flames turn yellow.

3. If flames are too "orange" or are causing sooting, open air shutters until flames begin to turn blue.

Important: Try each new shutter setting for approximately ½ hour before making additional changes. Note: Changes in front burner flame can be made by re-arranging the coals as well. Densely packed coals

will yield more glow and blue flames. Loosely packed coals will yield less glow and yellow flames.

Exhaust Damper

This fireplace is equipped with a vent damper system that can be adjusted using the glass latch tool. Locate damper adjustment rod above the glass frame in convection chamber at the center.

Note: If this fireplace’s vent is terminated vertically, the damper position may be full open or full closed. If this fireplace’s vent is terminated horizontally, do not close the vent damper completely. Adjust position of damper by judging the flame characteristics after 30 minutes of burn time. If the flames ghost off burners or if sooting occurs, open the vent damper fully and work backward in increments to determine the correct damper position for that particular installation.

REAR BUR N ER AD JUSTM EN T

FR O NT BUR N ER AD JU STM EN T

Page 57

FV36 85-03-01014

To adjust the exhaust damper, use a flashlight to look into the convection air cavity and note the damper position indicator. Hook glass latch tool in the hole at the end of the damper rod, pull outward about ⅛” and turn clockwise to close the vent damper, release. Use a flashlight to inspect the damper position. The base of the damper adjustment rod has a pointer that indicates the position of the damper.

Normal Flame Height

Troubleshooting Flame Appearance

Issue: A change in flame

appearance or burner operation

Possible Cause: A. A change in gas

pressure B. Vent system restricted C. Leaking glass gasket

Corrective Action: Have your gas supplier check for correct gas (7" WC Nat. Gas; 11" WC

LP gas). Clean out carbon, spider webs, lint, etc. from shutter area. Logs and burner. Check vent cap’s air intake and exhaust outlet ports. Check glass gasket for proper seal. Corners of glass gaskets cannot

be bulging out. If glass gasket along top edge in the middle is white in color across entire thickness of gasket bulb, replace glass gasket.

REPLACEMENT PARTS and SERVICE

Over Firing of Burner

Never "over fire" units by adjusting gas pressure or drilling out the orifice to increase Btu/hr above nameplate specifications. Over firing can cause permanent damage to firebox and deterioration of parts and void warranty.

Maintaining Correct Pilot-Flame, Pilot Outage, and Relighting

The pilot flame must be checked during initial installation and annually by a qualified Mendota Technician. This fireplace uses flame rectification technology. If the pilot flame is turned down too low, the flame sensor may not detect the pilot flame and the pilot may not stay lit. Do not turn down the pilot flame. The flame sensor rod may be coated with debris after a few months of use. It is important to clean the flame sensor rod using emery cloth if flame rectification problems are encountered after use for a few months. Environmental factors beyond the control of Mendota can cause flame rectification concerns.

How to Access Components

The descriptions below show where the main fireplaces components are located and how to access them for service. The descriptions show how to access the components after the fireplace has been installed. All components are also accessible from the outside of the unit before the fireplace is installed.

Pilot: The pilot is in the center of the firebox between the burners. Gas Valve: The main gas valve is located on the left side of the firebox. An inspection panel is provided on the

left firebox wall that allows inspection of the gas valve, wiring, and gas inlet connections. Complete Valve Assembly: To make working on components easier, this fireplace has been designed with

the valve, pilot, shutter boxes, shutter cables and gas lines as part of one assemble that can be removed from the fireplace. To remove the assembly first remove the inspection panel. This will allow the main gas inlet and wires to the valve, rear burner solenoid and pilot to be disconnected. After disconnecting the gas line and wires remove the screws from the valve mounting plate (13 on the left side and two on the floor of the firebox). Then remove the entire assembly from the firebox.

Ignition Control Module: The ignition control module is mounted on the left on the floor under a heat shield. Access to the ignition control module is available through the inspection panel. First remove the inspection panel. Then locate the two screws holding the heat shield in place above the ignition control module. The ignition control module is affixed with Velcro to the floor.

IPI and CPI Modes

Intermittent Pilot and Continuous (Standing) Pilot Features

This gas fireplace is equipped with an electronic ignition system that first lights a pilot then uses the pilot to ignite the main burners. The pilot can be set in the CPI (Continuous Pilot Ignition) mode to allow the pilot to remain on indefinitely by setting the remote control to CPI mode. If the remote control is set to the IPI (Intermittent Pilot Ignition) mode, the pilot will only light and remain ON while the main fireplace burners are operating.

IPI Mode: This mode turns the pilot off when the fireplace is not functioning and only lights the pilot automatically when a call for heat is made by the remote control.

CPI Mode: If set to CPI mode, the pilot will ignite and remain on at all times.

Setting to IPI or CPI mode

With the remote control off, press the MODE button. You will see either “CPI” or “IPI” displayed on the screen. Press the UP arrow button to set “CPI” mode

and press the down arrow button to set “IPI” mode. Once set to the desired setting, press On/Off button to activate the fireplace.

Note: The snowflake icon will be visible on the display at all times when in CPI mode.

Recommended: Mendota recommends keeping the fireplace in CPI mode. While not mandatory, this will keep the fireplace chimney heated for proper updraft during burner ignition, and it will also eliminate excessive condensation of exhaust vapors on the door glass. Leaving the fireplace in CPI mode will keep the fireplace body warm and eliminate cold drafts and heat loss to the cold air that is trapped inside the firebox.

FIRST-TIME LIGHTING INSTRUCTIONS

Safety Information

• This fireplace is equipped with an ignition device which automatically lights the pilot. Do not attempt to

light pilot by hand.

• Before operating, smell all around fireplace area for gas. Be sure to smell next to the floor because some

gas is heavier than air and will settle on the floor.

• Toggle master switch to on. Fireplace burners will not ignite unless the master switch is on.

• Use only the supplied remote control to light the pilot. This valve will not operate if the pilot is not lit and

stable.

• Do not use this fireplace if any part has been underwater. Immediately call a qualified service technician to

inspect and replace any component which has been under water. Attempted operation may result in fire or explosion resulting in property damage, personal injury, and loss of life.

Can I operate my fireplace during power outages?

This electronic ignition system uses the supplied 120VAC power when it is available for all functions of this system. If you experience a power outage, plug in the battery pack (6V DC maximum, supplied with this fireplace) to the fireplace backup power inlet port.

During the power outage, the fireplace’s burner will function as well as the flame height adjustment. The fan and accent light, which are dependent on 120VAC power, will not function.

Your installer should demonstrate the backup DC power pack during power outages. Be sure to retain the DC battery pack and the connecting harness in a safe and secure place for use during power outages.

What maintenance is required for my Mendota?

Required Annual Maintenance

The following procedures must be performed each year by a qualified Mendota service person. Note: Any adjustments to burner, pilot, or logs must be done by a qualified Mendota service person.

Recommended steps for yearly maintenance:

1. Clean all lint and dust build-up around the control. Inspect the condition of any wiring under the burner for melting or damage. Clean flame sensor rod/hook using emery cloth. Vacuum all burner ports and pilot assembly.

2. Remove logs and coals and clean away any foreign matter (lint, carbon, etc.) on the burner and logs. Be sure the burner ports are "open". Clean the pilot and under side of the logs for any carbon deposits. Note: Logs should be visually checked for carbon buildup. If carbon deposits are visible on logs, unit should be turned off and Mendota service person contacted. Be sure logs are re-installed per instructions.

3. Check condition of glass door gasket, gasket must seal tightly over firebox, Inspect gasket along top and sides of glass. If gasket at corners of glass are bulging outward or if gasket bulb along top edge or sides are discolored to a white color appearance through the whole thickness of the gasket bulb, then replace the gasket. White colored gasket bulb indicates exhaust leak through the discolored area and requires replacement of the glass gasket.

Periodic Inspection

Follow these steps for periodic inspections:

1. Check to verify that the vent system and vent cap are open and free of blockage.

2. The viewing glass should be cleaned periodically. To clean glass surface, use Kel Kem Polish Plus (part #65-06-00455) or a comparable product. Do not use oven cleaner or abrasive cleaners to clean glass. Do not clean when glass is hot.

3. Before re-installing glass, have qualified service person check the operation of the pilot and cycle the burner per lighting instructions. Be sure all items in lighting and installation checklists are completed.

4. Periodic visual check of pilot flames is required. Pilot flame must overlap flame sensor and burner ignition ports at all times. Especially for LP gas applications, always verify visible pilot flame length is at least 1" long.

5. Periodic visual check of main burner’s rear and front flames is required.

FV36 85-03-01014

How do I clean the viewing glass?

The viewing glass should be cleaned periodically. Exterior glass surface may be cleaned with cleaner as desired. To clean interior surface of glass, use soap and water. Caution: Do not use oven cleaner or ammoniabased products to clean glass. Clean the glass only when it has cooled to room temperature.

Additives that are put in gas (both natural and LP) to make it smell can be harmful to glass and can leave a white film deposit on the glass. This deposit can be removed with cleaners such as KEL KEM “Polish Plus” (part #65-06-00455) or comparable product. Contact your Mendota dealer for more information.

Is my flame performance correct?

Your fireplace has air shutters, dampers, coals, and embers that can be adjusted depending on your fuel and venting configuration. These adjustments should be made by a qualified Mendota technician to achieve the best flame performance. Contact your installer or Mendota dealer if you feel your fireplace is not burning correctly. Improper setup and adjustment is not covered under warranty.

What should I do if my fireplace is sooting?

Sooting is caused by improper installation or air shutter operation. However, some small areas of soot deposits on log surfaces are deemed acceptable. If you observe large soot areas (larger than 1”x1”) on log surfaces or signs of sooting on the door glass (usually a thin black film on the fireplace viewing glass or on the outside of the home around the vent cap), the unit must be immediately turned off and the local Mendota dealer promptly informed. Mendota dealers will correct "sooting" problems, but Mendota and their dealers are not responsible for damage caused by excessive sooting that has not been immediately brought to their attention.

Troubleshooting soot:

Issue: Thin black coating (soot)

forms on viewing glass.

Possible Causes: A. Incorrect gas pressure B. Not enough combustion

air C. Leaking glass gasket D. Vent obstruction

Corrective Action: Have gas supplier check for correct gas inlet pressure (7" WC nat. gas;

11" WC LP gas). Check glass gasket for proper seal. Corners of glass gaskets cannot be bulging out. If glass gasket along top edge in the middle is white in color across entire thickness of gasket bulb, replace glass gasket.

If sooting continues, open air shutter on burner. If sooting continues, shut off unit and call Mendota service person.

Note: To clean glass, remove glass and wipe glass with cloth or paper towel.

How do I change from Celsius to Fahrenheit on my remote?

To change between °C to °F, follow these steps:

1. Press the ON/OFF button and turn off the fireplace.

2. Simultaneously, press both the mode button and the thermostat button.

3. Look at the LCD display to verify that your desired indicator (°F or °C) is being displayed.

If not, repeat Step 2.

What happens when I first light my fireplace?

When you first light your fireplace, there is a curing period. This can include a small amount of smoke and odor. This is normal. Curing steps for your Mendota include:

Step 1: Expelling Initial Smoke and Odors

• Complete the installation of any surround, front, doors, or safety screen.

• Turn on the fireplace in the Manual (Off) thermostat mode.

• Set the flame height to Hi.

• Set the fan speed control to Level 3.

• Run the fireplace with these settings for a minimum of 2 hours. Then turn off the fireplace and let it

cool.

Step 2: High Heat Curing Cycle

• Turn on the fireplace in the Manual (Off) thermostat mode.

• Set the flame height to Hi.

• Set the fan speed control to Off.

• If any new curing odors are detected, continue to run the fireplace with this setting until the curing

odors have diminished.

Attention: Slight odors may still be noticeable on future startups of the fireplace. These will diminish over time as the fireplace is used.

Additional Curing Information

It is not unusual for a fireplace to require more than 10 continuous hours on high for curing odors to diminish. There are variables that can extend or shorten the curing time, such as decorative fronts, doors,

facing materials, and their applications. Finish materials around the fireplace are subject to high temperatures. Finishing materials used over the
